Abstract: A process for preparing a membrane stack comprising the steps of: (i) interposing a curable adhesive between alternate anion exchange membranes and cation exchange; and (ii) curing the adhesive; CHARACTERIZED IN THAT said adhesive, when cured, has a Shore A hardness of less than 70 and an elongation at break of at least 50%.

Abstract: A process for preparing a membrane stack comprising the steps of (i) interposing a curable adhesive between alternate anion exchange membranes and cation exchange; and (ii) curing the adhesive; CHARACTERIZED IN THAT said membranes are in a swollen state when step (ii) is performed.

Abstract: A membrane envelope stack for gas separation comprising membrane envelopes bonded together by means of an adhesive having a tensile E-modulus of at least 1600 N/mm2 and/or an elongation at break of 20% or less and/or a Tg of at least 50° C.

Abstract: A membrane envelope comprising a feed spacer, one or more membrane sheets and an adhesive, to give a glue line laminate having a tensile E-modulus of at least 1600 N/mm2 and/or an elongation at break of 13% or less.

Abstract: A gas separation module comprising: (a) a permeate collection tube; (b) a membrane envelope wound spirally around the tube to provide a wound membrane structure comprising two end faces; and (c) an anti-telescoping device (ATD) secured to the permeate collection tube, the ATD comprising: (i) an inner peripheral part, (ii) an outer peripheral part which surrounds the inner peripheral part, (iii) one or more connection parts which connect the inner peripheral part and the outer peripheral part and which contacts with one of said end faces; (iv) vents which allow gas to flow through the ATD; wherein the ATD satisfies Formula (1): (L CP?L contact)/(L VENT)=R Formula (1) wherein: R is from 1.47 to 1.88; L VENT is the cross sectional area of the vents which allow gas to flow through the ATD; L CP is the total area inside the outer peripheral part; and L contact is the contact area of the connection parts and the end face of the wound membrane envelope. Clamps are also claimed.

Abstract: The invention relates to a method for blocking roaming steering mechanisms. According to said method, a foreign cellular device (3), e.g. a cellular telephone, is registered with nationally visited radio network (2) when the foreign (1) and the national cellular network operator have concluded a roaming agreement on mutually debiting cellular services. The invention is characterized in that an anti-roaming steering server (5) installed in the nationally visited cellular network (2) identifies manipulated error messages (14) and selectively manipulates the registration process (8) of foreign mobile users by adequately influencing signaling processes.

Abstract: A method for informing a subscriber of a mobile telephony network about incoming calls while the mobile telephone of the subscriber is switched off or is not connected to the mobile telephony network. The notification takes place via the mobile telephone of the subscriber as soon as the mobile telephone has re-registered itself in the mobile radio network, and the message including at least the call number of the missed caller. In the event of a calling line identification restriction (CLIR) from the caller, a message is automatically produced and sent to the caller, by which means the caller is prompted, by a dialogue, to temporarily release the call number transmission for the call, such that the call number of the caller can be communicated to the subscriber.

Abstract: The invention relates to a method for delivering a short message in a mobile communications system, in which the short message sent from a mobile station is received by an SMS-Service-Centre, SMS-C, and forwarded to a corresponding recipient, wherein the SMS-C is addressed by means of an SMS-C address in the mobile communications system. The invention is distinguished by the fact that an SMS-C address recognized as erroneous is corrected on the part of the mobile communications system, and the delivery of the short message is continued with the corrected SMS-C address.

Abstract: The invention relates to a method for setting up a mobile radio connection to a mobile station (MS) in a cellular mobile radio network. According to said method, each cell of the mobile radio network can be identified by an identification character and a plurality of cells form a localisation area of the mobile radio network. In order to localise the mobile station (MS) inside a localisation area, paging is regularly carried out from a switching centre (MSC) in pre-definable time intervals, and a first mobile radio connection to the mobile station (MS) is set up by the paging, whereupon a paging response message is generated from the mobile station (MS) and transmitted over the existing first radio connection.
